hi geordie, I totally understand how you are feeling now, and I can guarantee that you will feel the same way for the rest of your life, but it will be less and less apart of your waking moments as the years progress, but for now, you can't do anymore than let your emotions out and take what support you can get, because if you try to question how you should or shouldn't respond you will then be trying to over analyse basic human emotions. i lived from day to day after mum died and when life started to improve dad died, and ir starts again, ust do what you want to do and accept help and support when it is offered. You go to work and see how you feel, people will probably not know how to react to you at first, death is not easy to talk about , which is amazing when you realise we all have to face it. Try not to go of sick though, it will make it ten times harder to get back to things.
Do your weeping at home , it is surprisingly comforting
